PUMPING ArrAnA'rUs.

Application filed July 21,

To all whom it mag concern; I

Be it known that I, IVA C. BELL, citizen of the United States ofAmerica, residing at Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in Pumping Apparatus,of which the following is a specification.

This invention relates to new and useful improvements" in pumpingapparatuses.

The invention has to do with that type of ,pumping apparatuses whereinthe liquid is A further object is' to reduce lost motion and-to utilizesubstantially all of the applied power.

' Another object is to provide an apparatus for-elevating any liquidsuch as oil, water and the like with any fluid pressure such as steam,air and-the like.

A construction deslgned to carry out the invention will be hereinafterdescribed to-- gether with other features of the invention.

The invention will be more readily understood from a reading ofthefollowing specification and by reference to the accompanying drawingsin which an example of the invention is shown, and wherein:

Fig. 1. is a diagrammatical vertical sectional view of an apparatusexemplifying the invention,

' I Fig. 2 is a cross-sectional view on the line 22 of Fig. 1, r Fig. 3is a cross-sectional view on the line 3-3 of Fig. 1,

Fig. 4 is an enlarged view'of thevalve controlling head, and j Fig. 5 isa transverse sectional view taken on the line 55 of Fig. 4.

In the drawings the numeral 10' designates a transverse manifold fromthe top of which:

vertical cylinders 11 and 12 respectively ex tend upwardly; whilevertical cylinders 11' and12' depend from the bottom of the'mani fold.The upper and lower cylinders are axially alined and while the lowercylinders j are-of less diameter, they are concentrically disposed withrelation to the upper cylinders. Each lower cylinder has a check valve13 in its bottom which is otherwise closed.

1924. Serial No. 727,307.

Liquid conducting pipes 14 and 15 respec-.

tively' extend from the lower ends of the I lower cylinders to the upperends of the upper cylinders, in crossed relation. The pipe 14 extendsfrom the cylinders 11' to the cylinder 12; while the pipe 15 extendsfrom the cylinder 12 to the cylinder 11. The pipes 14 and 15 each have acheck valve 16 at their lower ends.

In each upper cylinder is a piston head 17 connected by a piston rod 18with a piston head 19 in the lower cylinder thereunder. The pipes 14 and15 and the rods 18 pass through the manifold. A deflector 20 is disposedin the manifold between the cylinders 11 and 12. At the upper end ofeach upper cylinder is an exterior by-pass pipe 21, having its endsentering the cylinder. Each pipe is long enpliliglfi to by-pass fluidfrom.

above to he reaches the upper purpose'of the y liquid below head 17 andthus maintain a solidicolumn of liquid between the heads- Unless somemeans was provided for restor- -pass pipe 21 is to supply 1 ing theliquid which .leakspast the piston rings, the solid column andbalance,would be lost." Also these by-pass pipes afiord means for initiallyfilling the cylinders between the heads 17 and 19.

The parts 17, 18 and 19 will be referred to as pistons and these pistonswork oppositely, that is one is up when-the other is and when-fluid isforce'dout of a lower cylinder by the .down stroke of the piston it willbe displaced through the pipe 14 or '15 into the top of the uppercylinder, with which the pipe is connected.

excess of fluid from one uppercylinder will be forced throughthemanifold to the other upper cylinder, the excess being due to thegreater capacity of the upper cylinders.

From; this it will be seen that the pistons are balanced and only enoughpressure need has a plied onthe down stroke to displace t e ui Alsoupon-the down stroke of a piston the I A extends upwardly, while a pipe23 extends 22 and 23 will also be filled. Thus any dls- From the top ofthe cylinder 11 a pipe 22 upwardly from the cylinder 12. These pipesenter a valve housing 24. The pipe 22 con- H nects with the bottom of avtwo-way valve case 25; while the pipe 23 connects with the bottom of atwo-way valve case 26. A 'discharge pipe 27 leads from the case.25,while a similar pipe 28 leads from thecase 26. A fluid pressure supplypipe29 has branches leading to the'cases and entering at points spacedapart about ninety degrees.

In the case 25 is a rotatable gate 25' and a similar gate 26' is mountedin the case 26. The discharge pipes lead from the cases at substantiallyninety degrees from the'entrance of the pipes 22 and 23. The gates havetheir shafts 31 connected with arms 32 exteriorly of the housing (Fig.4). These enters the valve cases and 26. The gate ,7 26 cuts oil theescape of the fluid .from the arms have their upper ends pivoted to aconnecting bar 33, whereby-they are swung in unison. A shifting lever 34'is fulcru'med on a stud 35 on the side of the housing 24 and has a slot36 at its upper end receiving a headed pin 37 As is shown in underpressure supplied from the pipe 29 case 26, but permits the elevatingliquid from the pipe 23 to'discharge through the pipe 28. The fluidunder pressure from the case 25 passes into the pipe 22, the discharge27 being cut oil by the gate 25. The fluid pressure depresses the pistonin-the cylinders 11 and 11.

. When the piston starts down as described the valve 13 at the bottom ofthe cylinder 11' is closed and the valve 16 is opened, thus theliquidbelow the head 19 in said cylinder is forced out through the pipe14 into the top of the cylinder 12. The liquid below the head 17 in thecylinder 11 fills the cylinder 11' above the head 19 as the pistondescends, but as the capacity of the cylinder 11 is considerably greaterthan that of the cylinder 11', there will be an excess or surplus ofliquid which will be displaced into the manifold and the cylinder 12.This displacement will be suflicient to counterbalance the piston in thecylinders 12 and 12', which will be elevated in proportion to thedescent of the first piston. v I

As the piston in the cylinders 12 and 12' is elevated it will displacethe ffluid above the head 17 in the cylinder 12 as well as the. liquidentering from the pipe 114. I This' .liquid will be elevated in the ipe23 and discharged from the-pipe 28. ile the piston in the cylinder 11 isdescending the pipe 15 having been previously-filled, will be so held.While the pisten-iinrt egcylinder 12 is rising it will draw in liquld'tlirough the valve 13 in the bottom of said cylinder. At all times asolid body of liquid-will be pres- Fig. the elevating fluid lent on bothsides of the piston heads 17 and 19 and they will counterbalance. Thepipes placement of the liquid will also move the the lower slotted endof'the lever 34. The

left hand end. (Fig. l) of the cylinder is connected with the pipe 22 bya pipe 41; while a pipe 42 connects the pipe 23 with the right hand endof the cylinder. Each of the pipes 41 and 42 includes a spring pressedpressure valve 43.

As is shown in Fig. 1 the piston head 39 isat the left hand end of thecylinder 38. The pipes41 and 42 are small and the fluid entering saidpipes willunseat the valves 43 at a predetermined pressure. So long asliquid is being elevated in the pipe 23 atpipes 41 full capacity thepressure in the and '42 will be substantially equal and the piston willbe held in the cylinder 38 as is shown, but when the pressure in thepipe 22 becomes greater at the endbfthe up stroke of the piston in thecylinder 12, the fluid from the pipe 41 will enter the right hand end ofthe cylinder 38 and displace the piston head 39, thus shifting the lever34 and valves.

It is pointed out that the pipes and cylinders of the pump need not bearranged as shown in the drawings and any suitable and 1' operablearrangement may be made as the conditions of the wellmayrequire.
